ISO 17184-2014 PDF

Full title and description

ISO 17184:2014 — Soil quality — Determination of carbon and nitrogen by near-infrared spectrometry (NIRS). Specifies a rapid, non‑destructive method to estimate soil carbon and nitrogen content from direct measurement of near‑infrared reflectance spectra and an evaluated calibration model derived from reference methods.

Abstract

ISO 17184:2014 describes the application of near‑infrared spectrometry (NIRS) for the determination of carbon and nitrogen in soils. The standard covers direct measurement of sample spectra in the near‑infrared spectral region and the evaluation of these spectra using an appropriate calibration model developed from values obtained by established reference methods. The procedure provides a fast, non‑destructive estimate useful for screening and routine monitoring.

Scope

Specifies a method for the determination of carbon and nitrogen in soils by direct measurement of sample spectra in the near‑infrared spectral region. The spectra are evaluated by a suitable calibration model derived from the results obtained by reference methods; the method is intended for estimation and screening rather than replacing primary reference techniques.

Key topics and requirements

• Use of near‑infrared reflectance spectroscopy (NIRS) to estimate soil carbon and nitrogen content.
• Development and application of calibration models based on results from validated reference methods.
• Guidance on sample presentation and spectral measurement in the NIR region.
• Intended use for rapid screening, routine monitoring and large‑scale surveys where fast throughput is required.
• Notes on limitations: accuracy depends on quality of calibration and representativeness of reference data; complementary reference analyses remain necessary for calibration and verification.

Typical use and users

Laboratories and organizations performing soil monitoring, agronomy and environmental assessments; research institutes using rapid screening methods; national and regional soil survey agencies; commercial soil testing providers who implement or develop NIRS calibrations to increase throughput and reduce per‑sample costs.

Related standards

ISO 17184:2014 sits within the ISO "soil quality" family and is commonly used alongside physical sampling and reference methods, for example ISO 10694 (determination of organic and total carbon by dry combustion) and members of the ISO 10381 / ISO 18400 series for soil sampling and sampling guidance. Newer or complementary carbon/TOC standards and method developments (e.g., emerging ISO documents on carbon differentiation) may also be relevant when establishing calibrations and reference data.

FAQ

Q: What is this standard?

A: ISO 17184:2014 is an International Standard that specifies a near‑infrared spectrometric method (NIRS) for estimating carbon and nitrogen in soils.

Q: What does it cover?

A: It covers the measurement of NIR spectra from soil samples and the evaluation of those spectra using calibration models derived from reference methods to estimate soil carbon and nitrogen contents; it is intended for rapid screening and routine applications rather than to replace primary reference techniques.

Q: Who typically uses it?

A: Soil testing laboratories, research institutions, agronomists, environmental monitoring agencies, and commercial providers of soil analysis who need higher throughput and rapid screening tools.

Q: Is it current or superseded?

A: As of ISO metadata, ISO 17184:2014 is published and was last reviewed/confirmed in the ISO lifecycle; it is listed as "to be revised" (systematic review outcome) and a revision (ISO/DIS 17184 or other follow‑on documents) has been indicated as under development. Users should check the latest ISO catalogue or national standards bodies for any revision or replacement published after 2014.

Q: Is it part of a series?

A: Yes — it is part of the broader ISO soil quality collection of standards (sampling, physical and chemical determination methods). Commonly referenced companion standards include sampling guidance (ISO 10381 / ISO 18400 series) and reference carbon analysis methods such as ISO 10694.

Q: What are the key keywords?

A: Soil quality, near‑infrared spectrometry, NIRS, carbon, nitrogen, calibration, soil analysis, rapid screening.
